Specification of Letters Patent.

Patented May 12, 1914.

Serial No. 637,967.

Application filed July 11, 1911.

To all whom it may concern Be it known that I, CHRISTOPHER SMITH, a citizen of the United States, residing at Orrville, in the county of Wayne and State of Ohio, have invented a new and useful lVrench, of which the following is a specification.

It is the object of the present invention to provide a quick-acting pipe wrench, in which novel means are fprovided for effecting a rapid shifting o the movable jaw, means being provided for holding the movable jaw at its ad'usted positions, and for giving to the move le jaw, after it has been set approximately, a further movement to enga e with the work.

A further object of the invention is to provide novel means for mounting the movable jaw, both for longitudinal slidm movement and tiltably, and to rovide nove means for actuating the movable jaw to engage the work.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changesi-n the recise embodiment of invention herein disc osed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,-Figure 1 is a side elevation, parts being broken away; Fig. 2 is an edge elevation; and Fig. 3 is an elevation showingthe abuttingjfaces of the adjusting nuts.

The wrench herein disclosed comprises, as a primary and fundamental element, a shank 1, broadened adjacent one end, as shown at 2, the outer edge of the broadened portion 2 of the shank being serrated, to form a fixed 'aw 3.

Adjacent t e fixed jaw 3, the shank 1 is provided with spaced, parallel ears 4, preferably, although not necessarily, formed integrally with the shank 1. The ears 4 are supplied with openings 5, inwhich is j ournaledfor rotation, a head 6, the head 6 having an opening 7 therethrough, which opening 7 is located between the ears 4, and is parallel to them. In the head 6 there is another opening 8, at right angles to the opening 7 andat right angles to the planes of the ears 4.

The invention further includes a pair of nuts, denoted bythe numeral 9, the nuts 9 being threaded internally, as shown at 10. Parts of the threaded portions 10 of the nuts 9 are cut-away, so as to define channels 11 through the nuts. In their meeting faces, the nuts 9 are supplied with interengaging shoulders 12.

The nuts 9 are adapted to be placededgew1se 1n the opening 8 of the head 6, the openings through the nuts, under such circumstances, being alined with the opening 7 through the head. The nuts, when thus posltroned, are adapted to receive a jawcarrymg member 14:, consisting of a shank 15, of unequal transverse dimensions. The narrower edge faces of the shank 15 are threaded, as shown at 16, to engage with the threaded portions 10 of the nuts 9. The wider edge faces of the shank 15 are smooth, as shown at 17. The shank 15 carries at its outer end, a serrated movable jaw 18, adapted to coiiperatc with the fixed jaw 3.

In the shank 1 there is a recess 19, into which extends a pin 20, bearing against the shank 15 of the jaw-carrying member 14. Seated in the recess 19, and engaged with the in 20, is a spring 21.

Tie split nut 9 may be replaced by the ordinary single nut with either a continuous or interrupted thread.

Suppose that it is desired to adjust the movable jaw 18 quickly. Under such circumstances, the shoulders 12 of the nuts 9 are brought into abutment. When the shoulders 12 are thus in abutment, the channels 11 of the nuts will'be alined. The alined channels 11 are then alined withthe longer transverse dimensions of the shank 15. Under such circumstances, the shank 15 may be moved longitudinally in the openin 7 of the head 6, and in the channels 11 of t e nuts 9, the threaded portions 10 of the nuts 9 being out of engagement with the shank. The movable jaw 18 is then brought into close relation with the work, whereupon, by rotatin one or both of the nuts 9, the threads 10 o the nuts 9 will be brought into engagement with the threads 16 of the shank 15, the jaw 18 being set firmly a ainst the work, and being there held by the interengagement between the tl reads of the nuts and of the threads of the shank 15.

Owin to the fact that the head ,6 is mounts for rotation in the openings 5 of the ears 4, it is obvious that the head, together with the jaw-carryin member 14 may be tilted, to alter the ang e between the jaws 18 and 3. The spring 21, thrusting the pin 20 against the jaw-carrying members 14,

serves to hold the movable jaw 18 yieldingly A wrench comprising a shank having a fixed jaw; a head carried by the shank and provided with an opening; a movable jaw including a shank slidable in the head and threaded upon its opposite edges; superposed nuts held in the opening and threaded to engage the threads of the shank,parts of the threads of the nuts 'bein permit a slidin of the sham the nuts being lndependentlyrotatable and being provided upon their inner end faces with outstanding shoulders projecting in opposite directions, the, side faces of the shoulders being adapted to coact to aline the cutaway portions of the threads of the nuts, each nut lyin outside of the contour cut away to .of the other nut w ereby one nut maybe rotated without actuating the other nut until the side faces of the shoulders come into contact. I In testimon that I claim the foregoing as my own, I ave hereto afiixed my signature in the presence of two witnesses. v CHRISTOPHER SMITH. Witnesses:
